Common Use Case or Symptoms:

Order this when a small loader or dozer runs hot with a clean fan and good belts, or when the core is weeping at a tube - a copper and brass core of this age has usually been soldered once already, and a second repair rarely holds.

Why Choose Broken Tractor?

• ✅ Flow Rates On Record: 30 litres per minute of water and 28.2 kg per minute of air - figures Caterpillar publishes for almost nothing else in this family.
• ✅ Copper And Brass: Traditional construction that a radiator shop can solder and repair, unlike the aluminium and steel cores on later machines.
• ✅ Twenty One Pound Core: The lightest core in the section, easy to handle single-handed on a small machine.
